FIELD OF THE DISCLOSURE

The present disclosure relates to solid agroformulations and methods of preparing the same. More particularly, the present disclosure relates to extruded pesticide granules including a urea carrier and at least one pesticide active agent that when mixed with water form long term stable near micro-emulsions suitable for pesticide application. The present disclosure also relates to methods of preparing and using the solid agroformulations.

BACKGROUND OF THE DISCLOSURE

Crop and pest protection agents have conventionally been formulated in solid or liquid compositions, usually in the form of a concentrate for ease of handling and transportation. The concentrate is generally diluted with water by the user before application. Many liquid formulations in the form of emulsifiable or near-emulsifiable concentrates may contain a very high proportion of organic solvents (often up to 80 percent), which are increasingly coming under scrutiny for their potential negative effect on the environment.

Water-based suspension concentrates, which are another conventionally available form, are often viscous giving rise to handling problems and loss of active ingredient through retention in the packaging. Solid formulations, which may also be commercially available, can also have disadvantages; the more common granules and powders in particular can be difficult to measure but more importantly can be dusty and pose inhalation hazards for the formulator and the user. Tablets have not been used extensively because they are often slow to dissolve. In addition, solid formulations have been found generally to possess a lower biological activity than liquid formulations. Also, with unsophisticated mixing techniques at the site of use, the tendency of solid forms not to disperse immediately can cause not only clogging of spray equipment with undispersed formulation, but also an inadequate application of active ingredient to the crop or area to be treated.

Based on the foregoing, there is a need for fast-dispersing, solid pesticide formulations which have improved handling characteristics and enhanced biological activity over conventional forms, to satisfy both environmental concerns and provide an effective pesticidal product with commercially acceptable levels of stability for long term use.

SUMMARY OF THE DISCLOSURE

The present disclosure is directed to solid agroformulations, and in particular extruded pesticide granules, and liquid aqueous pesticide formulations including these granules. The extruded pesticide granules include a urea carrier in combination with a non-ionic surfactant, at least one pesticide active ingredient, and a small amount of residual water. This novel combination of components, when extruded as described herein, rapidly dissolves in room temperature water with gentle agitation to form a near micro-emulsion that has only a very slight haze that is substantially resistant to settling out of materials. In many embodiments, the extruded pesticide granules as described herein will dissolve in two minutes or less in room temperature water with gentle agitation. Because of these significant dissolution properties and the formation of a near micro-emulsion and retardation of settling for many days, the extruded pesticide granules described herein may be easily mixed and used “on site” thus improving the usefulness of the agroformulation. Additionally, various extruded pesticide granules including different pesticide active agents may easily be used in combination to form “on site” or other customized blends of two or more pesticide active agents to address various problems with a single aqueous formulation.

The present disclosure is further directed to an extruded pesticide granular composition comprising urea, a non-ionic surfactant, a pesticide active ingredient, and water.

The present disclosure is further directed to an extruded pesticide granule comprising from about 70 wt. % to about 80 wt. % urea pearls, from about 5 wt. % to about 10 wt. % of a non-ionic surfactant having a molecular weight of from about 14,000 to about 15,000 Daltons, from about 5 wt. % to about 10 wt. % pesticide active ingredient, and less than 3% water.

The present disclosure is further directed to a process for preparing an extruded pesticide granule. The process comprises melting a non-ionic surfactant, dissolving a pesticide active into the molten non-ionic surfactant, introducing urea, adding water, and mixing to form a mixture, extruding the mixture to form an extrudate, and drying the extrudate to form the extruded pesticide granule.

The present disclosure is further directed to a process for preparing an extruded pesticide granule. The process comprises introducing urea into water to substantially wet the urea, introducing a substantially water soluble pesticide active agent into the wetted urea, adding a nonionic surfactant to produce a mixture, extruding the mixture to form an extrudate, and drying the extrudate to form the extruded pesticide granule.

The present disclosure is further directed to an aqueous pesticide composition comprising at least one substantially water soluble pesticide active agent, wherein the aqueous pesticide composition is a near micro-emulsion.

The present disclosure is further directed to an extruded pesticide granular composition. The composition comprises first extruded pesticide granules and second extruded pesticide granules, wherein the first extruded pesticide granules include a pesticide different from a pesticide in the second extruded pesticide granules.

The present disclosure is further directed to a method for controlling phytopathogenic fungi and/or undesired vegetation and/or undesired attack by insects or mites and/or for regulating the growth of plants, where an extruded pesticide granular composition of the present disclosure is allowed to act on the respective pests, their environment or on the crop plants to be protected from the respective pests, on the soil and/or on undesired plants and/or on the crop plants and/or their environment.

It has been unexpectedly found that extruded pesticide granules that form highly desirable and stable near micro-emulsions in water can be suitably produced with one or more substantially soluble or substantially insoluble pesticide active agents in combination with a urea-based carrier material and a non-ionic surfactant. Surprisingly, by incorporating urea as the carrier material, the extruded pesticide granule has excellent dissolution/dispersion characteristics in water and forms a near micro-emulsion with only a very slight haze that is stable for many days upon mixing. Additionally, a suitable amount of the extruded pesticide granule can be incorporated into water in two minutes or less with only gentle agitation. Importantly, either water-soluble or water-insoluble, or a combination of both, pesticide active ingredients can be used in the disclosed extruded pesticide granules.

Additionally, the extruded pesticide granules and methods of the present disclosure provide numerous other advantages, including improved biological efficacy and lower dose rates for controlling pests; ability to be easily prepared to be organic compound-free; and ability to be easily transported to a work site and mixed with water onsite for easy and convenient application. Also, through the use of the specific components described herein for preparing the extruded pesticide granules, an approximate 66% reduction in the amount of water used during extrusion can be obtained without any negative impact on the resulting product. This has a positive environmental impact.

Furthermore, it has been unexpectedly found that in many embodiments the energy from the extrusion process used to form the extruded pesticide granules results in the dissolution of additional urea within the formulation, which moderates the temperature by slightly cooling the mixture. After the extrusion is complete, the slight excess urea in the solution begins to re-crystallize, thus releasing heat. This heat release gradually warms the extruded granules to actually assist in the drying process of the extruded granules. Such warming has been unexpectedly found to dry the granules to a water lever of about 3% to about 4% (by weight). This self-drying reduces the amount of overall drying required to produce the final extruded pesticide granule.

DETAILED DESCRIPTION OF THE DISCLOSURE

The extruded pesticide granules of the present disclosure provide for an easily mixable pesticide granule that dissolves/suspends in water at suitable pesticide concentrations to form a near micro-emulsion that this stable for many days or even a week. The extruded pesticide granules include one or more pesticide active ingredients in combination with a non-ionic surfactant and urea, optionally in the form or urea pearls. This unique combination of components is easily extruded to form the extruded pesticide granules that have numerous desirable characteristics and uses. In many embodiments of the present disclosure, the extruded pesticide granules are organic solvent-free extruded pesticide granules.

The extruded granules as described herein may include a substantially water soluble pesticide active agent, a substantially water insoluble pesticide active agent, or a combination of a substantially water soluble pesticide active agent and a substantially water insoluble pesticide active agent. Because the extruded granules can be formulated to include a single pesticide active agent, or various combinations of two or more pesticide active agents, the present disclosure provides a cost effective and simple means for providing customized blends of extruded pesticide granules including two or more pesticide active agents that, when combined with water, form a near micro-emulsion that is stable for application and includes a desired customized blend of pesticide active agents. The extruded pesticide granules also allow for easy transport as they are granular solids that do not need to be transported in water, thus reducing the weight of the product for transport and allowing multiple different types of granules (i.e., granules with different pesticide active agents) to be easily transported, mixed together, introduced into water, and utilized. In some embodiments, a near micro-emulsion aqueous pesticide combination may be formulated by including two or more different extruded granules that include different pesticide active agents.

These and other optional elements or limitations of the extruded pesticide granules and methods of the present disclosure are described in detail hereinafter.

The term “near micro-emulsion” as used herein refers to an aqueous pesticide active agent-containing solution that, upon preparation and for a period of at least 24 hours, forms a slightly hazy, substantially sediment-free solution that light can pass through, but through which objects cannot be made out. When compared to a micro-emulsion, which includes solutions that are clear and through which objects can easily be made out, and an emulsion, which is milky and through which light does not pass through and objects cannot be made out, a “near micro-emulsion” falls in between these two and is in its own class of emulsions.

The term “pesticide” as used herein refers to at least one active substance selected from the group of the fungicides, insecticides, nematicides, herbicides, safeners, growth regulators and combinations thereof. Preferred pesticides for use within the scope of the present disclosure include fungicides, insecticides, and herbicides.

Numerical ranges as used herein are intended to include every number and subset of numbers within that range, whether specifically disclosed or not. Further, these numerical ranges should be construed as providing support for a claim directed to any number or subset of numbers in that range. For example, a disclosure of from 1 to 10 should be construed as supporting a range of from 2 to 8, from 3 to 7, from 5 to 6, from 1 to 9, from 3.6 to 4.6, from 3.5 to 9.9, and so forth.

All combinations of method or process steps as used herein can be performed in any order, unless otherwise specified or clearly implied to the contrary by the context in which the referenced combination is made.

The extruded pesticide granules and corresponding manufacturing methods and uses of the present disclosure can comprise, consist of, or consist essentially of the essential elements and limitations of the disclosure as described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful in pesticide applications.

Pesticide Active Ingredient

The extruded pesticide granules described herein include at least one pesticide active ingredient. In some embodiments, the extruded pesticide granules will include two, three or more pesticide active ingredients. Suitable pesticide active ingredients include both substantially water-soluble (pesticide has a solubility in water of at least 10 g/L, preferably at least 25 g/L, and in particular at least 35 g/L) and substantially water-insoluble (pesticide has a solubility in water of up to 10 g/L, including up to 2 g/L, and in particular up to 0.5 g/L at 20 C) pesticide active ingredients, although the pesticide active ingredient should be substantially or completely soluble in the non-ionic surfactant described herein such that there is no milling required of the pesticide active ingredient. Insecticide active ingredients are particularly preferred within the scope of the present disclosure.

The non-ionic surfactant is desirably a non-ionic amphiphilic polyalkoxylate surfactant free of ionic groups that has a melting point of 55° C. or more. The polyalkoxylate is amphiphilic, which usually means that is has surfactant properties and lowers the surface tension of water. Usually, the polyalkoxylate is obtainable by alkoxylation using alkyleneoxides, such as C2-C6-alkylene oxide, preferably ethylene oxide, propylene oxide, or butylene oxide. Examples of suitable polyalkoxylates are block polymers or compounds such as alcohols, alkylphenols, amines, amides, arylphenols, fatty acids or fatty acid esters which have been alkoxylated with 1 to 50 equivalents.

The non-ionic surfactant may have a melting point of at least 35° C., preferably at least 43° C., more preferably at least 48° C. and in particular at least 50° C. and in particular at least 55° C.

The non-ionic surfactant is usually substantially soluble in water at 20° C. Desirably, the solubility in water of the non-ionic surfactant is at least 3 wt %, more preferably at least 7 wt %, and in particular at least 10 wt %.

The molecular weight of the non-ionic surfactant is typically in the range of from about 5,000 to about 50,000 Daltons, desirably from about 2,000 to about 35,000 Daltons, and desirably from about 5,000 to about 20,000 Daltons In one particular embodiment, the molecular weight of the non-ionic surfactant is from about 14,000 Daltons to about 15,000 Daltons.

The non-ionic surfactant is desirably a block polymer, which may contain a hydrophilic block and a hydrophobic block. Suitable block polymers are block polymers of the A-B or A-B-A type comprising blocks of polyethylene oxide and polypropylene oxide, or of the A-B-C type comprising alkanol, polyethylene oxide and polypropylene oxide. Desirably, the non-ionic surfactant is a block polymer comprising at least one polyethoxylate block and at least one poly-C3-C5-alkoxylate block (e.g. polypropoxylate or polybutoxylate). In particular, the non-ionic surfactant may be a triblock polymer of A-B-A type comprising a polyethoxylate type A block and a poly-C3-C5-alkoxylate block (preferably polypropoxylate) type B block.

One particularly preferred non-ionic surfactant for use in the extruded pesticide granules of the present disclosure is Pluronic F127 (BASF Germany).

Manufacture of Extruded Pesticide Granules

The extruded pesticide granules described herein and capable forming a near micro-emulsion upon introduction into water and gentle agitation, can be manufactured using a conventional low pressure extrusion apparatus, including a low pressure dome extruder. In some embodiments, high pressure extruders may also be utilized within the scope of the present disclosure to produce suitable extruded pesticide granules.

In embodiments of the present disclosure where at least one substantially water-insoluble pesticide active agent is utilized (or a combination of at least one substantially water-insoluble pesticide active agent and a substantially water-soluble pesticide active agent), to prepare an extrudable mix for extrusion and subsequent drying, the surfactant or surfactants may be first melted at elevated temperature to provide a molten surfactant composition. A suitable temperature may be, for example, about 90 C. Into the molten surfactant is added the pesticide active ingredient, or pesticide active ingredient. The pesticide active ingredient (or active ingredients, if there is more than one) is mixed into the molten surfactant until the pesticide active ingredient is dissolved into the surfactant and a substantially homogeneous mixture is obtained.

Once a substantially homogeneous mixture of the molten surfactant and pesticide active ingredient is obtained, the carrier material (desirably urea in the form of powdered urea or urea pearls in many embodiments) is mixed in to prepare a substantially homogeneous mixture. Once this is completed, the desired amount of water is added and the resulting mixture thoroughly mixed and kneaded. Generally, from about 4 grams to about 10 grams, including from about 4 grams to about 8 grams, and desirably about 6 grams of water is added for each 100 grams of non-ionic surfactant, pesticide active ingredient, and carrier material (urea), to achieve the desired moisture content for extrusion of the mixture. This amount of water produces a damp powder that can then be suitably extruded through a low pressure dome extruder using, for example, a dome screen size of from about 0.5 mm to about 1.5 mm, including about 1.0 mm, depending upon the desired granule size. The temperature of the extruder may be, for example, from about 60° F. to about 100° F., including about 80° F. The resulting granules may then be dried using conventional means to produce the extruded pesticide granules that have a high solubility in water due to the formation of a near micro-emulsion.

In other embodiments where a substantially water soluble pesticide active agent is utilized, to prepare an extrudable mix for extrusion and subsequent drying, the carrier material (desirably urea in the form of powdered urea or urea pearls in many embodiments) is first mixed with a solvent, such as water, and the solvent is allowed to wet and partially dissolve the carrier material. It is desirable that the solvent completely wet out the carrier material for efficient granule formation. The carrier material (typically urea) is completely wetted in the formulation when the temperature quits dropping and begins to warm up. Thorough mixing is desirable. In many embodiments, the amount of solvent (typically water) will be between about 3% and about 5% of the total weight of all of the components utilized to formulate the extruded granules, as urea dissolves up to about 150% (by weight) in water.

Once the carrier material has been completely wetted with the solvent, the substantially water soluble pesticide active agent is mixed in to prepare a substantially homogeneous mixture. The substantially water soluble pesticide active agent will de-lump and disperse into the carrier material/solvent mixture as it slightly dissolves. After thorough mixing, a surfactant or surfactants is added to gel the slight excess solvent and prevent a “stiff dough” formation to desirably prepare a damp powder or wet cake that easily flows. The surfactant or surfactants also act as a lubricant for extrusion.

This damp powder or flowable wet cake can then be suitably extruded through a low pressure dome extruder as described above. The extrusion energy applied to the damp powder results in slightly more urea dissolving, which moderates the temperature by slightly cooling, which assists in keeping the temperature steady. After extrusion, the slight excess urea in the solution begins to recrystallize thereby releasing heat. The extruded granules then actually warm up and can dry themselves to the 3% (by weight) to 4% (by weight) range. The resulting granules may then be further dried using conventional means to produce the extruded pesticide granules that have a high solubility in water due to the formation of a near micro-emulsion.

These dried extruded pesticide granules can be used to prepare an aqueous tank mix, in which a pesticide in near micro-emulsion form wherein the particle size is generally below 1.0 micrometer, by introducing the extruded granules into water and applying gentle agitation. In many embodiments, the particle size will be less than 0.8 micrometers, or even less than 0.7 micrometers, or even less than 0.5 micrometers.

The dried extruded pesticide granules can be introduced into water to prepare the aqueous tank mix such that the resulting near micro-emulsion tank mix has a total pesticide active agent concentration level of from about 0.1% (by weight) to about 1% (by weight), including about 0.5% (by weight). In other embodiments, the near micro-emulsion tank mix may have a total pesticide active agent concentration of at least 0.05% (by weight), including at least 0.06% (by weight), including at least 0.07% (by weight), including at least 0.08% (by weight). The exact concentration of total pesticide active agent, as well as the number of different pesticide active agents present (from extruded granules including different pesticide active agents), may differ based on the desired use of the aqueous formation.

The mixing of the extruded pesticide granules and water may be done directly in a spraying apparatus containing a tank, or multiple tanks. The mixing may be done at a temperature of from about 5 C to about 50 C, desirably from about 10 C to about 30 C. The mixing may be done by adding the solid composition to the water already present in a tank and agitating.

The methods of the present disclosure further include methods of controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insects or mites and/or for regulating the growth of plants, where the extruded pesticide granules obtained by the methods as described herein are allowed to act upon the particular pests, their habitat or the plants to be protected from the particular pest, the soil and/or on undesired plants and/or the useful plants and/or their habitat.

A user may apply the extruded pesticide granules after preparing an aqueous tank mix usually from a pre-dosage device, a knapsack sprayer, a spray tank, a spray plane, or an irrigation system. In some embodiments, the agrochemical composition is made up with water, buffer, and/or further auxiliaries to the desired application concentration and the ready-to-use spray composition is obtained.

The disclosure furthermore relates to a method for controlling phytopathogenic fungi and/or undesired vegetation and/or undesired attack by insects or mites and/or for regulating the growth of plants, where the concentrate according to the invention or the emulsion according to the invention is allowed to act on the respective pests, their environment or on the crop plants to be protected from the respective pests, on the soil and/or on undesired plants and/or on the crop plants and/or their environment. In general, the therapeutic treatment of humans and animals is excluded from the method for controlling phytopathogenic fungi and/or undesired vegetation and/or undesired attack by insects or mites and/or for regulating the growth of plants.

When employed in crop protection, the application rates of the pesticides amount is from 0.001 to 2 kg per ha, preferably from 0.005 to 2 kg per ha, especially preferably from 0.05 to 0.9 kg per ha and in particular from 0.1 to 0.75 kg per ha, depending on the nature of the desired effect. In treatment of plant propagation materials such as seeds, e. g. by dusting, coating or drenching seed, amounts of active substance of from 0.1 to 1000 g, preferably from 1 to 1000 g, more preferably from 1 to 100 g and most preferably from 5 to 100 g, per 100 kg of plant propagation material (preferably seed) are generally required. When used in the protection of materials or stored products, the amount of active substance applied depends on the kind of application area and on the desired effect. Amounts customarily applied in the protection of materials are 0.001 g to 2 kg, preferably 0.005 g to 1 kg, of active substance per cubic meter of treated material.

Various types of oils, welters, adjuvants, fertilizers or micronutrients and further pesticides (for example herbicides, insecticides, fungicides, growth regulators, safeners) may be added to the emulsion in the form of a premix or optionally only shortly before use (tank mix). These agents can be admixed to the compositions according to the disclosure at a weight ratio of from 1:100 to 100:1, preferably from 1:10 to 10:1.

The user applies the composition according to the disclosure usually from a predosage device, a knapsack sprayer, a spray tank, a spray plane, or an irrigation system. Usually, the agrochemical composition is made up with water, buffer, and/or further auxiliaries to the desired application concentration and the ready-to-use spray liquor or the agrochemical composition according to the disclosure is thus obtained. Usually, 20 to 2000 liters, preferably 50 to 400 liters, of the ready-to-use spray liquor are applied per hectare of agricultural useful area.

The present embodiments are to be considered in all respects as illustrative and not restrictive and that all changes and equivalents also come within the description of the present disclosure. The following non-limiting examples will further illustrate the extruded pesticide compositions and methods of the present disclosure.

EXAMPLES

The following examples illustrate specific embodiments and/or features of the extruded pesticide granules of the present disclosure. The examples are given solely for the purpose of illustration and are not to be construed as limitations of the present disclosure, as many variations thereof are possible without departing from the spirit and scope of the disclosure. In addition to the specific components set forth in the Examples, each dried extruded pesticide granule described included a small amount of residual water, typically less than 2 wt. %, and more typically less than 1 wt. %.

Example 1

In this Example, extruded pesticide granules including one pesticide active agent suitable for preparing a near micro-emulsion in water were prepared.

20.00 grams of Pluronic F-127 non-ionic surfactant was melted at 90° C. to prepare a molten surfactant. To this molten surfactant was added 20.06 grams of alpha-cypermethrin and the resulting mixture stirred to provide a substantially homogeneous mixture of pesticide active and surfactant. To this substantially homogenous mixture was added 159.94 grams of urea (98% pearls) and the resulting blend kneaded well to produce a substantially homogenous mixture of pesticide active, surfactant, and urea. To this homogeneous mixture was added 12.0 grams of water and the resulting blend was mixed well. This produced a damp powder extrudable composition.

The damp powder was then extruded using a low pressure dome extruder having a 1 mm dome screen at a temperature of about 81° F. The resulting granules were dried at room temperature on a glass plate. The resulting dried granules had a specific gravity of about 0.5, and a cylindrical shape (about 1.2 mm×about 3 mm). The granules were about 10.03 wt. % pesticide active, about 10.0 wt. % non-ionic surfactant, and about 79.97 wt. % urea. The extruded granules can be added directly to water with gentle agitation to form a near micro-emulsion.

Example 2

In this Example, extruded pesticide granules including two pesticide active agents suitable for preparing a near micro-emulsion in water were prepared.

20.00 grams of Pluronic F-127 non-ionic surfactant was melted at 80° C. to prepare a molten surfactant. To this molten surfactant was added 20.24 grams of alpha-cypermethrin and the resulting mixture stirred to provide a substantially homogeneous mixture of pesticide active and surfactant. To this substantially homogenous mixture was added 119.31 grams of urea (98% pearls) and the resulting blend kneaded well until cool to produce a substantially homogenous mixture of pesticide active, surfactant, and urea. To this homogeneous mixture was uniformly blended in 40.44 grams of dinotefuran. To this uniformly blended mixture was added 6.0 grams of water and the resulting blend was mixed well. This produced a damp powder extrudable composition.

The damp powder was then extruded using a low pressure dome extruder having a 0.8 mm dome screen at a temperature of about 81° F. The resulting granules were dried at room temperature on a glass plate. The resulting dried granules had a specific gravity of about 0.5, and a cylindrical shape (about 1.2 mm×about 3 mm). The granules were about 10.12 wt. % alpha cypermethrin, about 10.0 wt. % non-ionic surfactant, about 20.22 wt. % dinotefuran, and about 59.65 wt. % urea. The extruded granules can be added directly to water with gentle agitation to form a near micro-emulsion.

Example 7

In this Example, the biological residual efficacy of extruded pesticide granules of the present disclosure was tested and compared to the efficacy of Phantom Termiticide-Insecticide and a control. Specifically, extruded pesticide granules as prepared in Example 3 and including about 10 wt. % chlorfenapyr and extruded pesticide granules as prepared in Example 3 and including about 20 wt. % chlorfenapyr we evaluated and compared to the Phantom and control (control was no chemical treatment).

The pesticides were tested against German cockroaches (Blattella germanica), bed bugs (Cimex lectularius), confused flour beetles (Tribolium castaneum), and house crickets (Acheta domesticus). This testing was a residual test on unpainted plywood and painted plywood (Behr white semi-gloss exterior paint). The insects were confined on the treated surfaces with various cups depending on the insect. Four replications were used with ten insects for each replication. The knockdown and mortality were recorded over time, as shown in the following Tables 1-4. Each test formulation was diluted with water to a 0.5 wt. % active level and applied with a DeVibiss atomizer set at 10 psi from 12 inches at the rate of 1 gallon of product per 1000 square feet. Both the extruded pesticide granules of the present disclosure tested form a near micro-emulsion in water. The tests were discontinued when the control mortality was above 20%.

As shown in the Tables 1-4 above, for cockroaches all of the treatments were effective (>90%) of both surfaces at 1 and 28 days after treatment. For bed bugs, the bed bugs were not controlled (not >90%) by Phantom SC. Both of the extruded pesticide granule formulation of the present disclosure performed well at 1 day after treatment. For the confused flour beetles, all of the treatments worked on both surfaces at day 1, with the exception of the 10% extruded pesticide granule on painted wood; however at 28 days after treatment, all of the products worked well on both surfaces. For the house crickets, all of the treatments worked on both surfaces at day 1. At day 30, the extruded pesticide granule formulations worked well on both surfaces while the Phantom SC worked well on the unpainted wood and did not work well on the painted wood.

Example 8

In this Example, a contact test for biological efficacy of extruded pesticide granules of the present disclosure was tested and compared to the efficacy of Phantom Termiticide-Insecticide and a control. Specifically, extruded pesticide granules as prepared in Example 3 and including about 10 wt. % chlorfenapyr and extruded pesticide granules as prepared in Example 3 and including about 20 wt. % chlorfenapyr we evaluated and compared to the Phantom and control (control was no chemical treatment).

The pesticides were tested against German cockroaches (Blattella germanica) and bed bugs (Cimex lectularius). This testing was a contact test. The insects were confined in cups, treated and moved to clean cups. Four replications were used with ten insects for each replication. The knockdown and mortality were recorded over time as shown in Tables 1-2. Each test formulation was diluted with water to a 0.25% or a 0.5 wt. % active level and applied with a DeVibiss atomizer set at 10 psi from 12 inches at the rate of 1 gallon of product per 1000 square feet. Both the extruded pesticide granules of the present disclosure tested form a near micro-emulsion in water.

At 5 days after treatment the Phantom and the 10% extruded pesticide granule had the best control.

Example 9

In this Example, extruded pesticide granules including one substantially water soluble pesticide active agent suitable for preparing a pesticide active agent-containing near micro-emulsion in water were prepared.

159.94 grams of urea (98% pearls) was introduced into 10 grams of water and then thoroughly mixed to allow the water to completely wet out the urea. Once the wetting of the urea was complete, 20.06 grams of dinotefuran was blended into the water/urea wetted mixture and mixed thoroughly. After mixing, 20 grams of Pluronic F-127 non-ionic surfactant was introduced and thoroughly mixed to produce a flowable wet cake that was suitable for extrusion.

The flowable wet cake was then extruded using a low pressure dome extruder having a 1 mm dome screen at a temperature of about 81° F. The resulting granules were dried at room temperature on a glass plate. The resulting dried granules had a specific gravity of about 0.5, and a cylindrical shape (about 1.2 mm×about 3 mm). The granules were about 10.03 wt. % pesticide active, about 10.0 wt. % non-ionic surfactant, and about 79.97 wt. % urea. The extruded granules can be added directly to water with gentle agitation to form a near micro-emulsion pesticide solution.
